My 82 yr dad had hip replacement surgery three weeks ago. After the surgery my dad has NOT being himself.... he was in the hospital for three weeks including the surgery.... when he was released and taken back home he became unstable, not recognizing us at times.... He has become very agitated and anxious... yesterday he fell and we had to take him back to the hospital, and now he has two broken ribs which one of them proferated one of his lungs .... He is in excruciating pain, on top of that they somehow hurt his hip and his leg is all messed up he is not able to move it. when yesterday he was able to stand and take few steps... Doctors can not give him strong medication for his pain, since he is very thin weighs 84-90 lbs.... We truly regret convincing him to have the surgery.
